FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 373,860, dated November 29, 1887. Application filed Novembcr17,1886. Serial No. 219,166. (No model.)

To all whom it may concern.-

Be it known that I, JOHN L. STEFFEY, a citizen of the United States,residing at Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Fastening Devices; and 'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the IO art to which it appertains to make and use the same.

My invention relates toanew and improved catch or fastening fordetachably uniting carriage-curtains to each other or to the side,top,

1'5 or other suitable portion of the carriage framework.

The object of my invention is to provide a device of this character which,while economical in cost of material and manufacture, shall be thoroughly satisfactory in operation and shall retain its efficiency after long-continued use. For the accomplishment of these ends I have devised the construction hereinafter described, and illustrated in the accompanying 2 drawings, wherein- Figure 1 represents a front view of my invention. Fig. 2 represents a rear view of the button-hole forming one element thereof. Fig. 3 represents a front view of the securing-button and its carrying-plate. Fig. 4 represents in perspective a detached view of the outer button-hole plate. Fig. 5 represents a like view of the inner button-hole plate. Fig. 6 represents a like view of the securing-button and its plate. Fig. 7 represents a sectional View of the complete device, parts being in elevation, said section being taken upon the line 8 80f Fig. 1; and Fig. 8 represents a section of the complete device, parts being in elevation, taken upon the line 7 7 of Fig. 1.

Similar letters of reference indicate similar parts throughout the several views.

A indicates a portion of the frame-work of the carriage-top, to which the curtain is de- 5 signed to be detachably secured by means of my improved device.

B indicates a plate, preferably of thin sheet metal, and having perforations, as bl), for the reception of the heads of screws 0 0, whereby said plate may be secured to the frame-work A.

Centrally the plate B is provided with a bev eled perforation for the reception of the shank e of the turn-button O, said button being adapted to turn freely within the perforation d as a bearing.

The fabric D is provided with button-holes at points oppositethe turn-buttons. Thesebuttonholes are incased and protected by the inner and outer plates,E and F,suitably perforated, as shown, to permit of. the passage of the turn-button through them in the fastening and unfastening operations.

The perforation in the plate E is atits middle portion,f, of a contour correspondingto that of the turn-button shank. At its ends 9 g the perforation is narrowed to conform more or less exactly with the thickness of the wings h h of the turn-button. The perforation Kof the outer plate, F, is of similar general outline, and by reason of this construction the-button-hole is prevented from havinga sliding or longitudinal movement with respect to the button-shank after the fastening is completed.

In effecting the fastening the button-hole is brought opposite the turn-button and in alignment with the wings h h. The turn-button is then slipped through the aperture,whereupon a revolution to the right or left will bring the wings h h transverse to the perforation Kof the upper or outer plate, F, as illustrated in Figs. 1, 7, and 8, thereby securing the fabric to the framework A. In order to securely lock the button in this position of adjustment against danger of accidental displacement,I have provided the upper or outer plate, F, with a central struck-up portion, on, and have indented the same with the cross groove or depression n. The edges 0 0 0 0 0f the perforation K are slightly bent or beveled insiliency of the metal causes it to rise, thereby locking the wings h h in said groove.

The plates E and F are firmly joined beyond the portionm and through the fabric of the curtain by means of securing-strips r r, passing through the perforations 3 and o o '0 of the plates. The presence of these strips, which are preferably located as near as possible to the outer periphery of the struck-up portion m, prevents the plate F as a whole from spreading laterally when the button is being revolved, and therefore adds materially to the resiliency of said portion m.

To unfasten the curtain, it is merely necessary to turn the button until it is once more in alignment with the perforation Kavhereupon the button-hole may be slipped off.

It is obvious that the plate B may be of some other form than that.illustrated in the drawings and that it may be attached to any other support than the carriage-frame and the same results be attained. I have not shown its attachment to another curtain or the like,as such mode of attachment is fully within the knowledge of those skilled in the art. It is evident, also,that the device as a whole may be used for many analogous purposes, such as for fastening physicians and surgeons cases, satchels, trunks, and the like. I desire therefore to be understood as contemplating the employment of my device for all the various uses to which it may be applicable, and with such modifications in the structure of the several parts as shall fairly fall within the scope of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A fastener for carriage-curtains and the like, consisting of a plate carrying a revoluble stud provided with wings,said plate being adapted for attachment to one of the bodies that are to be united,and a button-hole guard for the other body, having an outer plate provided with a central resilient struck-up portion, perforated to permit'the passage of the stud-wings and having a depression or groove therein transverse to the perforation,substantially as described.

2. A fastener for carriage-curtains and the like, consisting of a plate carrying a revoluble stud provided with wings, said plate being adapted for attachment to one of the bodies that are to be united, and abutton-hole guard for the other body, having an outer plate provided with a central resilient struck-up portion, perforated for the passage of the stud wings, the edges of the perforation being beveled,as described,said struck-up portion being also provided with a depression or groove transverse to the perforation, substantially as described.

3. A fastener for carriage-curtains and the like, consisting of the plate B, having the stud or button O,provided with wings h lathe plates E and F, perforated for the passage of said wings, said plate F being provided with the resilient struck-up portionm,having the transverse groove n, and the fastening strips s s, uniting the plates E and F through the intervening fabric,substantially as and for the purposes set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN L. STEFFEY.
